Microsoft has released the official ISO images for Windows 10 of version 21H2 for Insiders (build 19044.1202). The same version is currently available on the Release Preview channel. So now you can download the ISO you are interested in and do a clean install of the latest version of Windows 10.
Release Preview versions are fairly stable. Although it is a pre-release version, it has changes compared to the current "fixed" version. As with 20H2 and 21H1, the new 21H2 will be a small cumulative update for Windows 10 2004 with a few minor tweaks. All of the aforementioned versions of Windows 10 share the same code base.
